# Line + combinatorial number - math problems

#### Number of problems found: 5

• Lines How many lines can be draw with 8 points, if three points lie on one line and the other any three points do not lie on the same line?
• Circles How many different circles is determined by 9 points at the plane, if 6 of them lie in a straight line?
• Points in plane The plane is given 12 points, 5 of which is located on a straight line. How many different lines could by draw from this points?
• Points in space There are n points, of which no three lie on one line and no four lies on one plane. How many planes can be guided by these points? How many planes are there if there are five times more than the given points?
• Lines In how many points will intersect 14 different lines, where no two are parallel?
